Preface: About This Guide

•Chapter 11, “Dynamic Switching of 1000BASE-X and SGMII Standards” provides general guidelines for using the core to perform dynamic standards switching between 1000BASE-X and SGMII.

•Chapter 12, “Constraining the Core” defines the constraint requirements of the core.

•Chapter 13, “Interfacing to Other Cores” describes additional design considerations associated with implementing the core with the 1-Gigabit Ethernet MAC and Tri- Mode Ethernet MAC cores.

•Chapter 14, “Special Design Considerations” describes additional design considerations associated with implementing the core.

•Chapter 15, “Implementing the Design”describes how to simulate and implement your design containing the core.

•Appendix A, “Core Verification, Compliance, and Interoperability” describes how the core was verified.

•Appendix B, “Core Latency” defines the latency of the core.

•Appendix C, “Calculating the DCM Fixed Phase Shift Value” instructs the user about how to calculate the system timing requirements when using DCMs with the core.

•Appendix D, “1000BASE-X State Machines” serves as a reference for the basic operation of the 1000BASE-XIEEE 802.3 clause 36 transmitter and receiver state machines.

•Appendix E, “Rx Elastic Buffer Specifications” describes the depth of the Rx Elastic Buffers which are available with the core. The size of the buffer is related to the maximum frame size which the core can accommodate.

•Appendix F, “Debugging Guide” provides information for debugging the core within a system.
